Abstract

The utility model relates to an anti-unlocking lock cylinder. Belong to lock core technical field, including lock core housing and tapered end, lock core housing is connected with the tapered end, lock core housing's inside is equipped with a plurality of blade, there is the connecting piece inboard of tapered end through spring coupling, and is equipped with the arch on the connecting piece, set up the recess with protruding looks adaptation on the tapered end. A plurality of arc-shaped through grooves are formed in the surface of the lock cylinder shell at intervals, and one side of each blade is fixedly connected with a protruding block matched with the arc-shaped through groove. A spring is added in the blade and the lock head, and when the key is put in, the spring is stressed to press the bulge at one end into the groove of the lock head, so that the key can be rotated to unlock; the false key enters, and the blade is stirred from inside to outside as required, so that the spring cannot be pressed, the blade can only be rotated, the lock head cannot be rotated, and the anti-theft function of the lock cylinder is greatly improved.

Description

Anti-unlocking lock cylinder

Technical Field

The utility model belongs to the technical field of lock cylinders, and particularly relates to an anti-unlocking lock cylinder.

Background

The lock core adopts multiple anti-theft technologies, multiple special-shaped anti-pulling marbles prevent technical opening, and the lock core has high safety performance of preventing technical opening by matching with unique structural design of the marbles and the blades. The lock core is internally provided with a precise number marble and a special-shaped marble structure, and the lock core can be automatically locked under the condition that the number marble and the special-shaped marble must be simultaneously pulled when the technology is started, so that the technology is started without work.

Because the lock core blade is shifted through the key, can the unblock, unlocking tool utilizes the buckle in the false spoon to fix a position after inserting false spoon on the market, shifts the leaf through the activity screens, from inside to outside slowly rotates each blade until all blades are a straight line, and after rotatory false spoon buckle, unblank. Thereby causing the existing lock core to have poor anti-theft function.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an anti-unlocking lock cylinder, which solves the problems in the prior art.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides an prevent opening lock core, includes lock core casing and tapered end, lock core casing is connected with the tapered end, lock core casing's inside is equipped with a plurality of blade, there is the connecting piece inboard of tapered end through spring coupling, and is equipped with the arch on the connecting piece, set up the recess with protruding looks adaptation on the tapered end.

Preferably, a plurality of arc-shaped through grooves are formed in the surface of the lock cylinder shell at intervals, and a protruding block matched with the arc-shaped through grooves is fixedly connected to one side of each blade.

Preferably, the blade and the cylinder housing are both cylindrical structures.

Preferably, the middle part of the inner side of the lock head is provided with a through hole for connecting a spring.

Preferably, the protrusions and the grooves are respectively and correspondingly provided with two groups.

The utility model has the beneficial effects that: a spring is added in the blade and the lock head, and when the key is put in, the spring is stressed to press the bulge at one end into the groove of the lock head, so that the key can be rotated to unlock; the false key enters, and the blade is stirred from inside to outside as required, so that the spring cannot be pressed, the blade can only be rotated, the lock head cannot be rotated, and the anti-theft function of the lock cylinder is greatly improved.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

Fig. 2 is a schematic diagram of an explosion structure of the anti-unlocking lock cylinder.

In the drawings, the components represented by the respective reference numerals are listed below:

1. a lock cylinder housing; 2. a lock head; 3. a blade; 4. a spring; 5. a connecting member; 6. a protrusion; 7. a groove; 8. an arc-shaped through groove; 9. a bump; 10. and a through hole.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the utility model relates to an anti-unlocking lock cylinder, which comprises a lock cylinder shell 1 and a lock head 2, wherein the lock cylinder shell 1 is connected with the lock head, a plurality of blades 3 are arranged inside the lock cylinder shell 1, the inner side of the lock head is connected with a connecting piece 5 through a spring 4, a protrusion 6 is arranged on the connecting piece 5, and a groove 7 matched with the protrusion 6 is arranged on the lock head 2. The middle part of the inner side of the lock head 2 is provided with a through hole 10 for connecting the spring 4.

In the embodiment, when the false key enters the lock cylinder shell 1, the false key needs to stir the blade 3 from inside to outside, the spring 4 cannot be extruded, so that the lock head 2 cannot be driven to rotate together, and the lock cylinder cannot be opened, and a key matched with the false key enters the lock cylinder shell 1 and can push the spring 4, so that the protrusion 6 on the connecting piece 5 can be pushed into the groove 7 formed in the lock head 2, and the lock head 2 can be driven to rotate together;

a plurality of arc-shaped through grooves 8 are formed in the surface of the lock cylinder shell 1 at intervals, and one side of each blade 3 is fixedly connected with a lug 9 matched with the arc-shaped through groove 8. The lugs 9 can slide inside the arcuate through slots 8.
